Surface Area of a Plane Inside a Cylinder

The video tutorial explains how to find the surface area of a plane within a cylinder using calculus. It begins with a graphical representation of the problem, followed by setting up a double integral. The integral is then converted to polar coordinates for easier evaluation. The tutorial concludes with calculating the exact and approximate surface area, providing both a theoretical and practical understanding of the problem.
